careddi supercritical introduction of ethanol co-solvent for extraction

JOHNSTOWN, Ohio (June 9, 2020) - Press Release - Apeks Supercritical, a subsidiary of Gibraltar Industries, has announced improvements to its CO2 extraction process using ethanol as a co-solvent to improve extraction times and raw yields.

Apeks' co-solvent injection module immediately accelerates extraction versatility for any size processor by combining the tunability of CO2 with the functionality of ethanol. The process injects small amounts of ethanol into the CO2 extraction ( of cannabinoids to improve the yield of the extract. The injection of 5% by volume ethanol results in a 300% faster oil extraction rate and approximately 2% higher total yield. The method can increase efficiency by more than 100 percent while maintaining some selectivity and eliminating homogenization of the post-treatment antifreeze process.

"The co-solvent injection module is a perfect example of the unparalleled innovation, versatility and customer service that Apeks continues to provide," said Andy Joseph, founder and general manager of Apeks Supercritical. Now, a set of extraction parameters can be achieved not only by adjusting the pressure and temperature of the CO2, but also by increasing or decreasing the concentration of ethanol in the ethanol to extract the desired cannabinoids and terpenes while leaving the unwanted compounds in the feedstock. Streaming. For our customers, this is an important product."

With fewer employees due to the coronavirus pandemic, operators can use the co-solvent injection module to increase throughput and speed up extraction, resulting in the same productivity with fewer people in less time. Because the Apeks supercritical system is fully automated, no additional personnel are required to operate the system.

Throughout the process, all ethanol pumped into the CO2 system is retained without loss. This occurs as a result of saturation of the plant material, as occurs with typical ethanol extraction, leaving 10% or more ethanol in the plant material. The ethanol is soluble in a liquid of supercritical CO2, thus allowing any residual ethanol from the extractor to flow naturally to the separator during the recovery process.

Advantages of using co-solvents.

Improved product type diversity for customer creation
Volume: more efficient use of raw materials - ethanol can absorb anything that CO2 cannot bring
Subcritical extraction with ethanol co-solvent is approximately 175% faster and supercritical extraction is 300% faster
The ethanol co-solvent injection module follows the recent announcement that Gibraltar Industries, a leading provider of products and services for commercial greenhouse production and processing in North America, has acquired a second extraction manufacturer at its Delta Separation facility in California. The move brings together Delta, an emerging leader in ethanol extraction systems technology, and Apeks Supercritical, a pioneering CO2 extraction company based in Ohio, to create the industry's most versatile provider of customized plant extractions.

In the second half of 2019, Apeks Supercritical Technologies introduced ReFraction, the first truly intelligent technology in CO2 extraction that uses artificial intelligence to provide operators with unprecedented insight into what is happening inside the system to improve efficiency and customize yields in ways never before possible.
